So far we have l)een concerned with the vertical elements of 

 crustal movement, we now turn to the horizontal. Comparisons of 

 longitude and latitude measurement of bench marks disclose a 

 considerable discrepancy in the values of earlier and recent dates. 

 Assuming the triangulation base. Order II. A-G in Map, PI. XIIl. 

 as permanent and unaltered, the new geographic positions of bench 

 marks are calculated from actual observations in relation to tht^ 

 neighboring fixed triangulation base, as in Table. 



'J'he X signifies meridian direction, the Y that of parallels. Kos. 1-22, affixed on the ujjper 

 left-hand of the triangles in I'l. XIII. mark the position.s and the nimibers of the bench marks.
